Services:
• Field Investigation
• Laboratory Testing
• Concrete Testing
• Compressive Strength Testing
• Slump Testing
• Air Content Testing
Project Description:
Highway 407 is a busy private highway, running through multiple heavily populated regions of the Greater Toronto Area. The highway sees thousands of vehicles per day travelling East and West through the City. Due to the heavy traffic, and cost implications of road closures, any construction and maintenance that is required on the highway is of the utmost importance for the owners.
The summer season is the only time that major construction and maintenance and construction can be completed, and any maintenance completed during these times must be completed with an accelerated timeline. The concrete road panels making up Highway 407 require frequent maintenance to support traffic loads. When replacing these loads, fast curing concrete must be used to reduce land closure time, and therefore, concrete testing is important to indicate when these lanes can be opened once they reach the required strength.
AllRock Role
AllRock was retained to perform Materials Engineering services and Concrete Testing in Toronto for the project, due to it’s trusted and reliable services. AllRock first reviewed the concrete mix design and engineering specifications for the project. AllRock utilized it’s experience on similar projects involving concrete air, temperature, and slump testing in Toronto and Southern Ontario in order to execute the field test portion of the project.
In the field, AllRock completed slump and air testing of the fresh concrete of each truck to ensure the mix fell within the required specifications. At pre-determined intervals, AllRock’s technician’s then took for unconfined compressive strength (UCS) samples, and let them cure as per the CSA A23.1 requirements. Once cured, the samples were transported back to AllRock’s Toronto Laboratory for laboratory measurement and testing. The concrete results were then reported by AllRock’s Concrete Engineer in Toronto to the client.
